APPLETON – Gov. Scott Walker reacted to the felony indictment of fellow Republican Gov. Rick Perry of Texas while at a campaign stop in Appleton on Saturday.

A Texas grand jury indicted Perry Friday on two counts of abuse of power for making good on a veto threat. Perry, like Walker, is a possible 2016 presidential contender.

Walker urged his counterpart to remain "bold and aggressive" and that he can understand the pressure.

"The bottom line is I can completely understand being under attack from outside sources for political purposes and it appears that's what we're seeing in Texas," Walker said. "I'd encourage him to stick with the truth and point out where politics are being played."

Walker has been the subject of two separate John Doe investigations his supporters have called "politically motivated." No charges have been filed against Walker.

Asked about his own vetoes, Walker said he focuses the decision on policy.

In Wisconsin, the governor has a partial veto power, among the most powerful in the nation. He used it most recently to strike language about early voting hours.

"It's all about good policy. If we veto something, it's about protecting the taxpayers and to put them in a better position," Walker said. "Our track record is clear, we've used it sparingly. Just like for eight years as a county executive I used the line item veto to save taxpayers money and lower property taxes."
